Lighting string with extending lighting structure

ABSTRACT

The present invention relates to a lighting string with extending structure, which includes an electrical wire with several bulb assemblies and some lighting units connected by an extending wires. The lighting unit can emit light at a distance from the electrical wire of the lighting string that provides a special lighting effect with improvement. The lighting unit is also possible to connect with lighting fiber for further extension of light.

BACKGROUND OF THE INVENTION

[0001] A conventional lighting string usually includes an electricalwire, which connects with several bulb assemblies in interval. As thelighting string connects with power source, the bulb assembly will belightened for lighting decorative effect. Since the bulb assembly isconnected just around the electrical wire, the decorative light is alsocentralized around the wire that is without special feature.

[0002] Accordingly, the primary object of the invention is to provide alighting string with extending lighting structure, wherein some lightingunits are far from the electrical wire to provide an inventedimprovement. Now the features and advantages of the present inventionwill be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0007] Please refer to FIGS. 1 and 2, the present invention relates to alighting string (1), which has an electrical wire (11) and several bulbassemblies (12) connected with the wire (11) in interval. Some of thesaid bulb assembly has only a bulb holder (121) for connecting with ajoint (2) of an extending lighting structure. An extending wire (21) hasone end connected with the joint (2) and the other end connected with anIC board (31) in a lighting unit (3). The lighting unit (3) includes abase (32) and a shell (33) to cover the IC board (31), which is providedwith several bulbs (35). A sleeve (34) is received in the shell (33)above the bulb (35).

[0008] When the power is turned on, the current passes through theelectrical wire (11) and the extending wire (21) to the IC board (31)that controls the bulb (35) to light or to twinkle. It is found that thelighting unit (3) will be far from the electrical wire (11) to provide anovel and different lighting decorative effect. In FIGS. 3 and 4, thepresent invention can be modified in case to put a bunch of lightingfiber (4) or a transparent patterned decoration in the sleeve (34). Thelighting fiber (4) will lead the light of the bulb (35) to be emittedoutward alone each fiber that will obtain an all new decoration, whichis never seen before.

[0009] Accordingly, the present invention provides an invented structurewith improvement. It obviously gains the utility and novelty for patentand is thus applied.

What is claimed is:
 1. A lighting string with extending lightingstructure including an electrical wire and several bulb assembliesconnected on the electrical wire in interval, wherein the characteristicis some of the bulb assembly has only a bulb holder to engage with ajoint of a lighting structure, which includes a base and a shell toreceive therein an IC board having several bulbs thereon to become alighting unit; and an extending wire having one end connected with thesaid joint and the other end connected with the said IC board forconductive connection that makes the lighting unit being far from theelectrical.
 2. The lighting string with extending lighting structure asclaimed in claim 1, wherein a sleeve is received in the shell above thebulb on the IC board for centralizing the emitted light of the lightingunit.
 3. The lighting string with extending lighting structure asclaimed in claim 1, wherein a sleeve is received in the shell while abunch of lighting fiber or a transparent patterned decoration can beconnected with the sleeve.
